SAN FRANCISCO (AP), Golden Gate Bridge officials have set a date for the installation of a moveable median separating northbound and southbound traffic.

Bridge District General Manager Denis Mulligan says the bridge is scheduled to close after midnight on Saturday, Jan. 10 and reopen before 4 a.m. on Monday, Jan. 12 for the work. Officials had originally aimed to install the median in October, but decided on the January weekend because the bridge traditionally experiences light traffic then.

The $30 million project has been in the works for more than a decade. Officials say the moveable, steel and concrete median will help prevent head-on crashes. Traffic on the span is currently separated only by yellow plastic tubes.

The January shutdown will be the famed span's first construction-related closure. The bridge's sidewalks will remain open.
